Oil light comes on when the car is idleing or when I let off of the gas it blinks what could be the problem?

You are low on oil, or your oil is too old. Check oil in the motor when the car has been sitting for at least two hours. The light usually doesn't flash until you are more than 2 quarts low. Change your oil.

My 2002 Toyota camry oil light blinks when the car idls we changed toe oil sending unit and oil pump what can I do to get the oil light to stop flashing..

Hi,

The overheating and lack of cabin heat both point to a failed engine thermostat which would be stuck closed. At the warm up stage, the coolant stays in the engine block to bring the engine to efficient operating temperature, then it opens and circulates the coolant through the radiator and heat core. If the thermostat is stuck closed, the engine will overheat, and coolant will never reach the heater core, and you will not get cabin heat.

Blinking oil light at idle which goes away during driving could be a low oil level, but may also be a drop in oil pressue. You could have a clogged oil fliter (at best) pickup tube, or a failing oil pump.

there is always the possibility that you really have low oil pressure when you get this light, at idle the engines oil pump produces the least pressure and if there are problems then that is when it shows up, so have the oil pressure tested by a shop with a mechanical test gage, if the oil pressure is within spec then replace the oil pressure light sending unit on the engine, I don't recommend you drive this until u are sure of the pressure, u can SEVERELY damage the engine is the pressure is really low.

You need to reset your change oil warning light. To do this, turn the ignition key to on but do not turn over the engine. Then rapidly push down the gas pedal three times. This will reset the system and turn off the blinking light. Then when you drive another 3000 miles, that light will once again tell you it is time to have your oil changed. J.

Your oil sensor may be faulty, or your may have a leak since you said the fluid level is okay.

its a high mileage engine.
all you need to do is use a thicker oil and the light will go out at idle speeds.

use a 50w sae valvoline racing oil.
plus stp oil treatment.

do that and that light is all gone.

Sounds like your oil pressure sensor may be faulty. Or your oil level is very low. Your engine should idle as low as 650 rpm without your light coming on.

Just a idea. If the car is running at idle and the oil light blinks , it usually from low oil pressure. At a idle your seeing the light respond to the revolutions of the engine. ! thing to try is to replace the oil pressure switch on the engine block. And #2, Most causes in a VW is that the vehicle overheated at one time and weekend the oil pump,or massive amount of miles.

it sounds like your oil pump or your oil pick up might be blocked.
Try running an engine oil flush and changing your oil
